ETL Systems MUXL1P-4118 L-Band & 10 MHz Multiplexer with DC Pass 850–2150 MHz

ETL Systems MUXL1P-4118 L-Band & 10 MHz Multiplexer with DC Pass 850–2150 MHz

The ETL Systems MUXL1P-4118 combines an L-band RF signal and an externally supplied 10 MHz reference onto a common connection, or separates them into dedicated signal paths. It supports indoor satellite communications and RF distribution systems requiring DC continuity along the RF path.

The common port carries L-band RF, 10 MHz, and DC. The separate L-band port passes RF and DC while rejecting 10 MHz. The dedicated 10 MHz reference port is DC blocked. No separate DC injection connection is shown.

The DC path is rated at 500 mA, with a maximum DC voltage specification of 50 V on any RF port. Maximum RF input power is +21 dBm (125 mW).

Available configurations provide 50Ω SMA or 50Ω N-type connectors. The rugged, compact enclosure supports tapped screw and through-hole mounting.

This listing covers one MUXL1P-4118 multiplexer in the selected connector configuration. Reference sources, DC supplies, RF equipment, cables, and mounting accessories are sold separately unless included in the quoted configuration. The unit does not generate DC power or a 10 MHz reference.

The manufacturer’s V1.1 datasheet lists “±0.35 dB” under mean L-band insertion loss and labels a higher 0.8 dB reference-path loss value “Minimum.” Confirm the intended L-band loss/flatness specification and maximum 10 MHz insertion loss when requesting a quotation. RF input must remain within +21 dBm (125 mW).
